This disclosure relates to a method for slicing a cylindrical elastic body, for example, a slab or broad belt prior to being cut into belts or rings of a certain width, by a two-shaft system, and its apparatus. The apparatus includes a) a drive shaft, of which the top end thereof can be released from its support, of which the root end thereof is connected to its drive unit, the drive shaft having a radially projecting part at the root end; b) a freely rotatable shaft extending in parallel with and at a constant distance from the drive shaft in a horizontal plane, of which the top end can be released from it support and can be tilted in vertical direction, and c) a cutting unit which has a cutter positioned perpendicular to the axial direction of the drive shaft, and which can move towards the drive shaft and can travel in the axial direction of the drive shaft. With the use of the above-mentioned apparatus, a cylindrical elastic body can be reliably and stably biased to one end of the two shafts supporting the elastic body, and slicing into rings of a desired width can be accomplished with high precision.

Two-shaft method for slicing a cylindrical elastic body into rings and

This disclosure relates to a counter for elastic rings, comprising a screw having a spiral groove which is slightly wider than the width of an elastic ring and is slightly deeper than the thickness of the elastic ring. The screw has an open discharge end, and a plurality of sorting rollers are loosely mounted in series on a support shaft located above and parallel to the screw and are independently capable of rotation and vertical movement. The sorting rollers contact a spiral ridge of the screw, and are arranged such that while the screw is rotated and the elastic rings are fed to the feed end thereof, the elastic rings are loosely moved into the spiral groove of the screw by the sorting rollers, and then sequentially delivered from the discharge end of the screw to a counting means.
